APPENDIX 1 MEASURING BOILER EFFICIENCY
App 1-7 HHV is the higher heating value, hg is the enthalpy in Btu/lb of water vapour at 1 psi and the flue gas temperature (FGT) in °F, and hf is the enthalpy of water at the combustion air temperature (CAT) in °F. hg can be determined from steam tables or from the equation hg, Btu/lb = 1055 + (0.467 x FGT). hf can also be determined from steam tables, or from the simple relationship
